Summary

In the Linux kernel, the following vulnerability has been resolved:

ALSA: usb-audio: Fix an out-of-bounds bug in __snd_usb_parse_audio_interface()

There may be a bad USB audio device with a USB ID of (0x04fa, 0x4201) and the number of it's interfaces less than 4, an out-of-bounds read bug occurs when parsing the interface descriptor for this device.

Fix this by checking the number of interfaces.
